  1. 1. Mechanical behaviour of hardwoods : effects from cellular and cell wall structures

    Författare :Ingela Bjurhager; Lars Berglund; Ingo Burgert; Magnus Wålinder; KTH; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Wood fibre and forest products; Träfiber- och virkeslära;

    Sammanfattning : Syftet med den här avhandlingen var att undersöka mekaniska egenskaper hos olika arter av lövträd, och koppla egenskaperna till cell- och cellväggsstrukturen i materialet. Arterna som omfattades av undersökningen var Europeisk asp (Populus tremula), hybridasp (Populus tremula x Populus tremuloides) och ek (Quercus robur). LÄS MER

  4. 3. Colour Response in Drying of Nordic Hardwoods

    Författare :Stefan Stenudd; Thomas Thörnqvist; Timo Kärki; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; beech; Betula pendula; birch; CIELAB; discolouration; drying; Fagus sylvatica; log storage; oak; press drying; wood colour; Quercus robur; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : Colour and appearance of hardwood are of great importance for the interiorand furniture industry. The widespread use of transparent surface treatmentand a fashion that prescribe light colour on many species, means that deviationfrom the ideal have considerable impact on the industrial operations.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant ecology; Växtekologi; Deciduous; Dynamics; Forest management; Nutrient sustainability;

    Sammanfattning : This thesis considers several important aspects of nutrient dynamics and allocation in adult stands of Swedish forest tree species (Quercus robur L., Tilia cordata Mill., Fraxinus excelsior L., Betula pendula Roth. LÄS MER

  7. 5. Quality Aspects of Sliced Oak Lamellae in Development of Engineered Wood Flooring

    Författare :Victor Grubîi; Jimmy Johansson; Alexander Pfriem; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood slicing multi-layered flooring surface-checking climate test. hardwoods processing slicing lathe checks digital image correlation DIC image processing veneers; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : Valuable hardwoods, such as oak, although renewable, present limitations in product realisation in terms of their cost and availability, often attributed to production waste and sub-optimal product design factors. The slicing technique facilitates the production of thin wood lamellae, minimising waste and ensuring optimal material conversion. LÄS MER
